Creating Video Clips
Brightcove Engage™ provides the ability to create video clips from live events that are in progress and completed live events. There are several reasons you might want to create a clip:
- To create a short, teaser clip that can be posted to social media
- To limit the length of a video that you want to post (most platforms limit the length of videos)
- You have found that shorter videos perform better on social media
- Clips can only be created within 7 days of the event end. Afterwards, the Create Clip button will be disabled.
- Clipping is not supported on all browsers.
- Clips will be frame-accurate provided that the encoder is sending SMPTE timecodes for the stream - otherwise, they will be accurate within a couple of frames. Note that to provide clips as quickly as possible, a segment-accurate clip is first created, and replaced by a frame-accurate clip as soon as it is available.
- Clips with a start time less than 10 seconds into the stream cannot be created.
- Media sharing will fail for videos created by clipping Live streams.
- Clips cannot be created from AES encrypted live streams.
Navigating the clip editor
To open the clip editor, click Live in the navigation header, click on an event name and then click Create Clip in the left navigation. The clip editor will open.
Note that all times in the clipping interface are based around the UTC time that the video data was received by Brightcove.
The clip editor is organized as follows:
Creating a clip
Follow these steps to create a clip.
- Using the clipping buttons or shortcut keys, set the start and end points for the clip.
- Click Save.

- Clip Name - Name of the clip
- Short Description - Description of the clip
- Tags - Tags to associate with the clip
- Reference ID - Reference ID to assign to the clip
Any required custom fields will also be displayed.
- Click Create Clip. The processing for the clip will begin.
A list of all clips will appear below the clip editor. Clicking the Clip Name will open the clip on the Videos page in another browser tab.
The preview player is used to preview the clip. When the event is in progress and the clip editor is opened, the clip will begin to play from the "safe live point" which is approximately 3 segments before the end. Note that not all browsers support autoplay.
Playback control buttons
The playback control buttons are used to control to playback of the clip inside of the preview player.

The cue in and cue out points are the start and end of a clip. Each of these points is represented on the focus timeline with a draggable handle, and the time between the points is filled-in green. The points are also represented in the context timeline as the left and right edges of the green rectangle indicating the clip space.
